I ran a campaign a couple of years back.  I was on a very limited budget in terms of time, and was much less versed in map making than I am now.  I needed a map for the game, and didn’t have anything but MS Paint to make it in.  Sadly, that is what I did.  I wasn’t completely happy with it at the time, but at the same time I wasn’t overly disappointed in it.  The game went great and is remembered very fondly, and I’d like to think that the map played a role in that, but looking at it now makes me cringe a bit.  I decided to take a few minutes yesterday to spruce the map up a bit.  I didn’t redo the map, more renovated it a bit.   It limited what I could do, but also preserved the overall look of the original.
